Cut Off Ties? I Turned Around and Became the Top Scholar in the Imperial Examination!

After twenty years of wandering, once I returned home, I, the eldest son of the richest man, became a shame to my family. "Treason! Trash!" My biological father roared and kicked me out of the house and severed all ties with me! But they don't know that I came with a civilization! I am a doctor of liberal arts in the 21st century. Poems, songs, historical allusions, all are in my heart! You laugh at me because I am illiterate, but I have a skinny gold body and amaze everyone with my skills, which attracts the rich and powerful in the city to rush for me! You laugh at me for being penniless, but with a little trick, I can become as rich as the enemy! One day when I ascend to the court and take charge of the world, when the Su family kneels down and begs for mercy, then I will know what a proud man of heaven is!
